A supercell has reached Sopron from Austria, with heavy rainfall and lightning activity, which is expected to head southeast, with a small chance of a thunderstorm.
The cell is accompanied by strong wind gusts, heavy rainfall and hail, typically with ice particles below 2cm.
Until the evening, there is a chance of thunderstorms in the northern part of Transdanubia, mostly in the area bordered by Szombathely-Székesfehérvár-Mosonmagyaróvár.
More thunderstorms are coming behind the Sopron supercell, and a supercell has also formed near Ternitz based on radar and satellite images.
Another wave is expected late at night, with thunderstorms organized into the system, causing a lightning-fast night in much of the country.
